PACKAGE-MAKING 111M18 Application filed January 28, 1928." Serial 1Tb. 248,870,

This invention relates to a machine for automatically making, wrapping and hermetically sealing small individual articles into a package. By Way of illustration, but i not of limitation, I have chosen to illustrate my invention in the form of a machine, par-.

ticularly adapted to use in making, wrapping and hermetically sealing small discs of candy,

or the like, into a'roll of a well-known type now on the market. So far as I am aware, no machine has heretofore been devised for I doing, in one complete seguence of operations, what the herein disclose machine is capable of doing, and it is therefore the general object of my invention to rovide a machine such as herein disclosed or thepurpose of making up such a roll, covering it with a' suitable wrap er, and hermetically sealing the same and elivering the completed packages from the machine ready for the market.

Another object of my inventionis to provide a machine for doing the work set forth in the principal object, which is relatively simple and therefore inexpensive to manufacture. These'and other ancilliary objects will be clear to one skilled in this particular art, after a study of the specification taken in connection with the annexed drawing,.

' Referring to the details wherein like numloading bers refer to corresponding parts in the various views: 1 illustrates the base of the machine on one end of which is mounted frame members 2, from which project arms 3. Between the arms 3is. supported for rotation, a roll of paper 4:. This paper is preferably pretreated with a suitable grade of paraflin or its equivalent, for a purpose which will be hereinafter referred to. Carried by the frame members 2, is an idler roller 5. Also carried by the frame members 2 is a pair of feed rollers 6 and 7. The roller 7 is .adapted to be driven by any suitable means, as by a driving belt 8, and through the medium of gears 9 and 10, it drives the roller 6. Also mounted on the frame members 2 is a pair of spindles 11 and 12, on the end of the spindle 11 is a pulley 13, and on the end of the spindle 12 isa pulley 14, which are connected by suitable driving means, such as belts 15 and 16, with corresponding pulleys on the ends of the shafts carrying the gears 9 and 10. Also carried on the spindles 11 and 12 are additional pulleys 17, which may be adjustable thereon in any satisfactory manner as by a set screw 18, passing through a hub on the end of said pulleys.

Spaced apart. from the spindles 11 and 12, and corresponding pulleys 17, on another portion of the machine is a second set of spindles 19 and 20, and on these spindles are mounted pulleys 21 of the same size as the pulleys 17. The pulleys 21 are also adjustable on their spindles in the same manner p as the ullevs 17 By referrin to Figure 2 Figure 7 is a sectional view on the line it will e seen that the pulleys l and 21 may be adjusted laterally on their respective spindles so as to give any desired space and by making the pulleys of the split type the pair shown in the center in Figure 2, may be removed entirely, thereby leaving only two sets of pulleys. Passing over the pulleys 17 and 21, are belts 22 and 23, which are of a texture having a nap, such as velvet forthe purpose of securing the necessary carrying ability for the paper strips, as they come from the feed rolls 6 and 7. It is to be understood that the belts 22 and 23 as shown in Figure 1, are operated so that the lower half of the belt 22 is in engagement with the upper half of the belt 23 and the paper strips are thus held between these two edges of the belt, and carried forward thereby; In Figure 4 I have shown an enlarged sectional view through the rolls 6 and 7. The feed roller 7 is provided with a matrix 24, which may be of any suitable material, such as soft rubber, while the roll 6 carries a cutting knife 25. The cutting edge'of' the knife 25 is preferably made'serrated as indicated at 26 as I have found that this sort of cutting edge used in association with the matrix 24 gives the best results in cutting off the paper. The cutting blade 25 is held 'in position on the roll by a pair of screws 27, the ends of which screws pass through slots 28 in the cutting.

blade 25, which is resilientl held in the position shown in Figures 4 an 5 by a spring 29. As the rolls 6 and 7 are operated in the direction of the arrows, the cutting blade 25 is brought into engagement with the strip of paper 30 in the manner indicated in Figure 4,

and completely severed, that is to 'say, a,

length of paper is cut off, of a predetermined length according to the size of the package that is to be wrapped and sealed, which length is determined by the diameter of the feed roll 6.

Forming, sealing and wrapping mechanism Mounted on the base 1 of the machine, is a support member 31, which carries the spindles 19 and 20 previously referred to. The frame member 31 also carries a hub 32 withi1 which is positioned a bearing bushing 33. Mounted within the bearing bushing 33, is a sleeve 34, having a head 35, in engagement with one end of the bushing On the opposite end of the sleeve 34 is carried a driving pinion 36, having a hub 37, which by means of the set screw 38 serves to secure the pinion I support member 58, WlllCll carrles a pair of 36 to the sleeve 34. The end of the hub 37 preferably abuts against the end of the bushing 33, and hub 32 so as to hold these parts in proper working relationship. Carried within the sleeve 34 and securely attached thereto in any satisfactory manner, as by brazing is a hollow mandrel 39. The walls of the mandrel 39 are rather thin, of course depending on the character of the material that is to be formed into a package, and wrapped and sealed by the machine. For the purpose of small candies of the Life Saver type I have found that the Wall of the mandrel need be only about seven thousandths of an inch thick. The reason for this will be later apparent when the operation of formed integral therewith a series of cars 47,

between which are mounted small rollers 48. As shown in Figure 6, there are three sets of these rollers 48 arranged around the periphery of the shield 46. In Figure 2, only the top set of rollers and those on one side are shown for the purpose of clarity. The rollers 48 are so positioned around the shield as to be tangentialwith the mandrel 39, for a purpose which will be hereinafter explained.

Carried by the frame 1 is another support member 49. The support 49 carries a member 50, in a manner such that the member 50 may slide up and down in its support. Mounted on the lower end of the member 50 is a roller 51 which is adapted to be engaged by a cam 52 (see Figure 9), for the purpose of raising the member 50, which is provided member 50 is provided with a pair of binding posts 56 to which the wires of an electrical circuit may be connected for the purpose of conveying current to a heat element 57, which heats up the arms, forming the throat 53 for the purpose which will-be brought out during the description of the operation of the machine.

Mounted adjacent the support 49 is another rolls 59 (see Figure 3) these rolls are what I term longitudinal sealing rollers, and are provided with a heating means 60 for a similar purpose as the heater 57. The rollers 59 are so constructed and positioned that the axis 61 iis kicated in the longitudinal axis of the man- Transfer and secondary sealing and crimping mechanism Mounted on the machine is a conveyer 62, which is preferably composed of a plurality of chains-composed of links 63, two links being shown on an enlarged scale in Figure 8. Connected between the chains is a seriesof v the arrow (Figure 8). The movement'of the bars 64, on which are mounted receptacles 65, that'are adapted to receive the packages as they are ejected from the rolls 59. Each bar 64 is provided with a bearing 66, which carries a shaft 67 to the upper end of which is attached the receptacle 65, and on the lower end of which is provided a pulley 68 adapted to be engaged by-a belt 69,- which turns the various pulleys 68 and the receptacles 65 as the conveyer 62 is carried forward in the direction of pawl 73 to a lever 7 4, which in turn is connect-.

- ed by an arm 75 to the end of a crank arm 76.

The crank arm 76 is operated by the shaft 77, throu h the medium of the rocket wheel 78, and t is in turn is driven y a sprocket 79 (see Figure 2). It will be seen from what has just been said that as the shaft 77 is turned in the direction of the arrow, an intermittent movement is given to the belt or chain 72 and hence to the conveyer 62. The belt 69 may be operated in any satisfactory manner, but since it is operated at high speed, I prefer to operate it by an individual motor 80, connected to a shaft 81 with the ulley 82. In order to prevent any sag of the ielt 69, adjacent the pulley 68 I have provided a guide member 83, which acts to guide the ed e of the belt and insure that it makes a goo contact with the pulley 68. Associated with the conveyer 62, and in proximity to the high speed belt 69, there is a support arm 84, more or less yieldable, which carries a member 85, which is constructed in a somewhat similar-manner to the member 50. A throat 86 is provided for engaging the ends of the paper sticking upward from the roll 87, as the same is brought toward the throat 86 by the conveyer 62. The secondary sealing member is preferably provided with a heater 88 for the purpose hereinafter indicated.

Loading nwclzamlsm Referring to Figure 2, there'is shown adjacent to the flared end 44 of the mandrel 39, a conveyer 89, which preferably comprises a pair of sprocket chains operated by the sprocket wheels 90 and 91 which sprocket wheels may be operated in any satisfactory manner, by any of the driving wheels or shafts. Carried by the conveyer 89 is a series of carriers 92, preferably concave or cradle shaped, which act to cary the pieces 93 intermittently up to and in alignment with the loading mandrel 39. Mounted adjacent the conveyer 89 is a plunger 94, carried by an arm 95, the end of which is supported by a bracket 96. The plunger 94 is resiliently held in the arm 95 as by a spring 97. The arm 95 is adapted to be actuated by a lever 98 through the medium of a cam 99, acting on the end of the lever 98 which is pivoted at 102. The cam 99 is carried on the operating shaft 77 (see Figure 9). a v

Operation Coming now to the operation of my machine, the paraflin treated paper is withdrawn from the roll 4 and after over, the idler 5, is drawn between t e fee rollers 6 and 7, and cut off into pieces of a .pre-determined length as heretofore described. These pieces are then fed forward by the belts 22 and 23, as above described, ,up to the forming, sealing and printing mechanism. The ieces 30 are fed by the belts 22 and 23 un er the end of the shell 46 1 (Figure 6) and are immediately caught by one of the rollers 48 and the mandrel 39, the

mandrel39-bein 0 erated at a much higher speed thanthe ee belts 22 and'23, quickly jsnaps the pieces of paper 30 from these belts and wraps it around the mandrel, the paper is preferably of a width so that a pre-deterassin mined (portion of the paper-projects beyond the on of the mandrel 39. As the rolling operation is finished,;the cam 52 acts on the roller 51 and starts the primary crimping member 50 into motion upwardly so that the throat 53 engages the end of the paper and twists this, together as it. is spun around on' the mandrel, and as it is twisted, due to the heat applied by the heater 57, the araflin is melted and flows to'securely seal t e crimpings. While this is going on, the conveyor 89 is bringing up the pieces, discs of candy or articles to be formed and wrapped and as one of the cradles 92 is brought into alignment with the flared opening 44, of the mandrel, the cam 99 operating on the end 100 of the lever 98 operates the plunger 94 to. push the pieces 93 from the cradle 92 into the hollow mandrel 39, and against the crimperl end of the roll. of paper, and the continued movement of the plunger 94' pushes the roll or paper with the ieces of candy or other material" through t e mandrel, and between the rollers 59, which rolls the paper securely around'the pieces of candy or other material, and due to the heat'applied by the heater 60, the paraflin is melted and seals the entire outer surface of the roll. The plunger 94. has a stroke sufliciently long so that it pushes the entire package through the rollers 59 into the receptacle 65 as indicated in Figure 2, it being understood that at this instant the conveyer 62 is stationary. Immediately the roll 87 has been forced into the container 65, the

last crimped'end and the conveyer 62 moves the roll onward, drawing the crim ing roll out of the throat 86 and the roll 8? is complete and ready to be withdrawn from the receptacle 65. It is obvious that the rolls 87 ma? be automatically ejected from the receptac e 65, but the same has not been indicated on the drawing. From what has been said it will be obvious that many changes may be made in the details of my machine, without departing from the spirit of m invention and the scope of theappended c aims.
